I have been in touch with Bomar/ Pompanette, and have ordered new dogs and pins for some of my 8 opening portlights. 1983 Cherubini 25. The best part is that Pompanette now has a new and improved gasket for these older Cherub Hunter portlights. I ordered and have replaced all of my gaskets with the new gasket product, and my ports are now entirely leak-free. While doing this I cleaned out all of the port drains with a cable tie, which were clogged. Bomar Pompanette part# GP 904-09 replaces the old 5/16 round gasket.....it is "T" formed instead of round. Easy to replace all of them....significant repair...very easy to do. Not cheap, $5 a foot, but well worth it. Cappie
